Answer:
CS₂
Explanation:
To find the empirical formula we need to determine first the percentage of each atom in the molecule. Then, we need to find the moles and, as empirical formula is the simplest whole-number ratio of atoms we can solve the empirical formula:
<em>%C:</em>
0.33gC / 2.12g * 100 = 15.6%
<em>%S:</em>
1.53g S / 1.82g * 100 = 84.1%
In a basis of 100, the moles of each atom are:
<em>C:</em>
15.6g C * (1mol / 12.01g) = 1.30 moles
<em>S:</em>
84.1g S * (1mol / 32.065g) = 2.62 moles
The ratio of Sulphur-Carbon is:
2.62mol / 1.30mol = 2
That means empirical formula is:
<h3>CS₂</h3>
Answer:
CCl4
Explanation:
Because the size of the molecule and the inter molecular forces are greater than the others.
Answer:
B
Explanation:
solute is what gets dissolved in the solvent
ie: salt in water. salt is the salute and the more of it you add to the water (solvent) the more interactions will occur increasing rate
Answer:
b) maintains the pH of blood near 7.4.
c) regulates the blood pH at 7.4 +/- one pH unit.
f) is facilitated by the enzyme carbonic anhydrase, which interconverts carbon dioxide and water to carbonic acid (ionizes into bicarbonate and H^+).
Explanation:
The pH of human blood is slightly acidic i. e. 7.4. The enzyme carbonic anhydrase is responsible for the regulation to neutral and prevent it from acidic. the enzyme carbonic anhydrase helps in the conversion of carbon dioxide to carbonic acid and bicarbonate ions. When the blood reach to lungs, the bicarbonate ions convert back to CO2 and this carbondioxide is exhaled from the body.
